Arduino Pro Mini Programming Clamp

#ARDUINO PRO MINI Programming-Clamp
Arduino Pro Mini is a small, cheap Arduino-Board (below 1EUR). It has no USB, so you have to connect a external USB to serial-adaptor to program/log it. You can solder a 6 pin connector to the programming interface but why, you use it only for programming.
So i constructed a comfortable clamp with ICT-contacts, realising a shift mechanism (a ballpen-spring) with enables a "swimming" connection (board is holded by contact-spring and ballpen-spring in middle.
It´s very comfortable to adapt the Arduino.

Have also a look to the other construction: [Link](https://www.thingiverse.com/thing:4973180)
